The document discusses the use of "too" and "enough" when bargaining for a lower price. It explains that "too" is used to imply difficulty, as in "it's too cold to go outside", while "enough" refers to sufficiency, as in having enough food. Examples are provided to illustrate using "too" with adjectives like "tall" or "big" to indicate something exceeding a limit. The conclusion distinguishes that "too" means more than necessary while "enough" means sufficient.
